Question

The binding of a hormone to its receptor leads to the formation of a

• A. Second messenger.
• B. Primary messenger.
• C. Hormone-receptor complex.
• D. Intracellular messenger.

Answer 1

The correct option is C

Hormone-receptor complex.

The correct option is C.

Explanation for the correct option:

1. On target tissues, receptors are particular proteins that certain hormones bind to in order to have an impact.
2. A hormone-receptor complex is created when a hormone binds to a hormone receptor on the cell membrane or inside the cell.
3. Certain biochemical alterations in the target tissue are brought on by the formation of the hormone-receptor complex.

Explanation for the incorrect options:

Option A:

1. Second messengers are the molecules that aid in signal transmission.
2. The intracellular (inside the cell) signaling molecules are second messengers.
3. Cellular physiological changes like differentiation, migration, survival, proliferation, and other processes are sparked by second messengers.

Option B:

1. The extracellular signaling molecules, frequently hormones or neurotransmitters, are referred to as the first messenger system.
2. They may also be known as ligands. They interact with receptors on the cell surface.

Option D:

1. Intracellular receptors are those that are present inside the cell rather than on the cell membrane.
2. Traditional hormones that work with intracellular receptors are found in thyroid and steroid hormones.

Final answer: The binding of a hormone to its receptor leads to the formation of a hormone-receptor complex.
